Here's a simple implementation of the Game of Life as a single HTML file that you can play on a smartphone using pictograms:
To play the game: open the HTML file on a smartphone browser, and you'll see a grid of cells. Tap on the cells to toggle their state between alive and dead. The game will automatically update every second following the rules of the Game of Life. The alive cells are represented by darker cells, while the dead ones are lighter.
Note: This is a simple implementation of the Game of Life using a fixed grid size of 10x10. You can customize the grid size and appearance (e.g., using pictograms) according to your preference.
